// retry.rhai — retry patterns against a transient endpoint.
//
// Usage: recon --script retry [URL]
//
// Shows the --retry cluster via the http() opts map:
//   retry             : number of retries
//   retry_all_errors  : widen predicate to include 4xx / parse errors
//   retry_connrefused : retry ECONNREFUSED
//   retry_delay       : fixed delay (seconds); otherwise exponential backoff
//   retry_max_time    : total wall-clock budget

// starting a slow service.
